The SPT-3G+ receiver design
H. Athreya, Z. Ahmed, J. E. Austermann +71
We present the thermo-mechanical design of the cryostat and camera optics for SPT-3G+, a new receiver being developed for the South Pole Telescope (SPT). The receiver consists of 1…
Unified and consistent structure growth measurements from joint ACT, SPT and \textit{Planck} CMB lensing
Frank J. Qu, Fei Ge, W. L. Kimmy Wu +143
We present the tightest cosmic microwave background (CMB) lensing constraints to date on the growth of structure by combining CMB lensing measurements from the Atacama Cosmology Te…
Correlating Visual Characteristics and Cryogenic Performance of Superconducting Detectors
K. R. Ferguson, A. N. Bender, N. Whitehorn +1
Cryogenic characterization of transition-edge sensor (TES) bolometers is a time- and labor-intensive process. As new experiments deploy larger and larger arrays of TES bolometers,…
Optical leakage mitigation in ortho-mode transducer detectors for microwave applications
Riccardo Gualtieri, Peter S. Barry, Thomas Cecil +5
Planar ortho-mode transducers (OMTs) are a commonly used method of coupling optical signals between waveguides and on-chip circuitry and detectors. While the ideal OMT-waveguide co…
Performance of a low-parasitic frequency-domain multiplexing readout
A. E. Lowitz, A. N. Bender, P. Barry +14
Frequency-domain multiplexing is a readout technique for transition edge sensor bolometer arrays used on modern CMB experiments, including the SPT-3G receiver. Here, we present des…
ICE: a scalable, low-cost FPGA-based telescope signal processing and networking system
K. Bandura, A. N. Bender, J. F. Cliche +14
We present an overview of the 'ICE' hardware and software framework that implements large arrays of interconnected FPGA-based data acquisition, signal processing and networking nod…
